Quote: Easy to get high-end model (AK120/100, hifiman...) but lower-end are quite difficult. But already enjoying x3  , bass is not too much but very tight and UI is not very good but still better than C3

great comparison! thanks for that and I am now into the JDS labs O2 

Quote: well.. I will go try both in two different shops... sigh it is quite difficult to find a hifi store that selling DAP in Hong Kong 

Quote: But C4 is way out my budget

I have read through a lot of threads discussing on this, but I have no conclusion yet: some said LO will be better for amp, some said it is not really the case. so is this really a big difference between using PO & LO for amp?

Quote: But isn't C3 don't come with the LO? You mean using PO to connect the amp?

subbed! would it be good time to buy x3 now...

Hi guys I am considering to buy a DAC, and I am struggling on choosing C3 or X3, both have good quality, and X3 seem have a better UI, but colorfly sound like better than fiio. So any sharing on this? Thanks a lot~
